2-2 PJL Command Syntax and Format EN
Syntax Conventions
The following syntax conventions are used to describe the PJL
commands in this manual:
variables Items in italics indicate names of variables.
COMMANDS Items in uppercase letters indicate PJL command names
and words that you type verbatim. PJL command names
referred to in text are also in uppercase.
[ ] Items in brackets [ . . . ] indicate optional parameters. The
brackets themselves are not typed.
< > Identifies a control code character, such as <CR> for
carriage return, or a special defined identifier. The table on
the next page lists the control codes and special identifiers
used in the PJL syntax. (The < and > symbols themselves
are not typed, but are replaced with the control codes or
special identifiers they represent. For example, replace
<FF> with the form feed character [ASCII 12].)
~ This character indicates that the current line of code is a
continuation of the previous line. For example, “All of this
text belongs on the
~ same line.”
| A vertical bar indicates there is more than one optional
parameter, such as LPARM and IPARM: [LPARM :
personality | IPARM : port].
